Piston Position Calibration
The position sensor assigns a numeric value to the loca-
tion of the piston. Higher numbers indicate the piston is
extended and lower numbers indicate the piston is
retracted.
The Piston Position Calibration procedure teaches the
machine the location of the most extended piston posi-
tion ( ), the most retracted piston position ( ),
and the position where the piston engages the pump
cylinder ( ).
Perform the Piston Position Calibration procedure when
first setting up the machine. Also perform this procedure
if the linear position sensor, piston, or any electronic
component has been replaced.
Prepare Machine for Calibration
1. Ensure that both piston shafts are screwed all the
way into the drive block.
2. Ensure there is a sufficient amount of material in the
tanks.
3. Navigate to the Calibration screen. See Screen
Navigation Diagram, page 16.
4. Place a waste container under the dispense valve to
capture any dispensed material.
5. Ensure system air pressure relief switch (106) is in
the up position and the system air pressure
regulator (105) shows air pressure in the system.
Extended Piston Position
6. With air pressure applied to the machine, press the
Extend Piston button ( ).
7. Press the Start/Stop Shot button ( ). The piston
will fully extend and a number 3600-3900 should be
displayed. If a number significantly different from
3600-3900 is displayed, ensure the air cylinder air
line connections are not switched and that the linear
position sensor is installed correctly.
8. Press the Enter button ( ) to accept the new
value or press the Abort/Cancel button ( ) to
keep the previous value.

IG. 23: Calibration Screen
If the piston does not extend after pressing the
Start/Stop Shot button ( ) the air pressure may
need to be increased. Use system air pressure
regulator (105) to increase the air pressure in incre-
ments of 10 psi until the piston activates. Material
will be dispensed when adequate pressure is
achieved.
